Photoionization of the alkali molecular ions in geo-cosmical plasmas

Opacities of the solar and stellar atmospheres are caused by a large number of radiative processes. Within development of more sophisticated stellar atmosphere models, we can further investigate known processes and include all processes not considered before. We calculate the average cross-section and rate coefficients for the photodissociation of the alkali molecular ions Li+2 , Na + 2 and LiNa ready for further use with a particular accent to the applications for astro plasma research and low temperature laboratory plasma research.
